Computing in Distributed Environments.

The major goal of this research is to study the impact that global properties of a distributed environment and their local knowledge at each entity of the system have on the design of efficient distributed algorithms. Some of my goals are: to identify useful structural properties for efficiently solving a given problem, to exploit local knowledge for reducing the communication cost of a problem, to improve existing protocols or devise new ones by using appropriate choices in the design of the communication ports. Of particular interest are distributed mobile environments , where mobile entities inhabit a static system (e.g., software agents in a network); in this setting I am particularly concerned with security issues when computing in unsafe conditions.
Some of my research projects in this area include: distributed mobile computing in unsafe environments, distributed computing with sense of direction, dynamic monopolies …

Discrete Chaos.

I am also interested in the study of discrete dynamical systems. In this area, my main goal is the understanding of the notion of discrete chaos. In particular, I study the complex ``chaotic" behaviors of Cellular Automata (CA) following algebraic approaches and using dynamical tools and I am interested in some models (fuzzy CA, coupled map lattices) which exhibit complex behaviors.
